I just got my car back from the shop after they installed my Eibach Pro Kit and I'll tell you, I couldn't be more happier. I walked up to the shop and the car was sitting there waiting to be aligned and due to the drop, I asked myself "ah crap, how bad did I screw up this car" I was really afraid that the ride would be to harsh but let me tell you, it drive's just about as plush as it did stock, just a whole lot better. It rides much more stable, responsive tight and flat. I have scraped a couple times on a fairly steep driveway but it was more because I wasn't aware just how low it was.
I am real happy with the results. I was originaly going to go with Pdaft set up but because I also found them for just over 400 bucks, compared to twice that for the Pdaft, I went with Eibach.
Another reason I went with the Eibach Pro Kit was because it was model specific. All the other manufactures offer the same kit for both the V8 and V6, while eibach has a specific kit for each model.
